Yeah, talking can be a bit challenging and you also get a closed off feeling. But I never found them uncomfortable. Inserting them is really easy if you practice it a few times. And on the plus side they are nearly invisibleHi @Deamon22, thank you for your message. I tried foam earplugs already but I don't find them very comfortable, and it's not very easy to talk with them. I also find that they're not very easy to insert properly :/ So I hope those custom plugs would offer me more convenience ^^
But if you have no problem with the fitting of custom earplugs then go with them. Should be enough for most daily activities
